介绍利用工业废渣──烧结法生产氧化铝的赤泥和电厂的粉煤灰研制免蒸免烧砖的方法。经过多年的试验研究已完成试验室和工业生产线的扩大试验。废渣掺入量在５０％以上。产品的各项性能指标均已达到或超过了国家建材工业标准ＪＣ２３９－９１规定的非烧结普通粘土砖的７．５级砖标准。产品成本低于市售普通粘土烧结砖。 This paper introduces the method of using industry waste slag to produce red mud of alumina and fly ash of power plant to develop steam-free burning-free brick. After years of experimental research, the expansion test of the laboratory and industrial production lines has been completed. The amount of waste slag is more than 50%. All performance indicators of the products have reached or exceeded the 7.5 brick standard of non-sintered ordinary clay bricks specified by the national building material industry standard JC239-91. The product cost is lower than that of commercially available ordinary clay fired bricks.
